Re: [EnergyPlus_Support] Re: Constant Air Volume with Heat Recovery?

[Fred Buhl <wfbuhl@xxxxxxx>]

You can't replace the coils in the unitary systems with water coils. But 
in SmOff the
systems are modeled as individual components on an air loop. You would 
replace
the DXSystem:AirLoop with a chilled water coil and the COIL:Gas:Heating with
a hot water coil. An you would need to add a Controller:Simple to 
control each water
coil.
